Telecommunication Engineering

GENERAL The principles of operation of a radar system are introduced, for the detection, the estimation of distance, angle, Doppler frequency and amplitude and for the classification. The characteristics of radio-transceiver apparatus and their requirements are studied in depth, together with the characteristics of the radar signals processing chain, with their performance The relationships are assessed among radar systems, waveforms used, signal processing techniques, operating environment, and the achievable performance, aiming at the preliminary design of the system and its processing techniques and identifying guidelines for its design. Waveform compression for phase-modulated pulses, pulse integration, control of a constant false alarm rate and clutter cancellation techniques are studied in particular. The following are introduced: (i) search, tracking and navigation radar systems, with reference to the control of piloted and unpiloted air traffic, naval and road traffic; (ii) Proximity radar sensors for presence, occupancy, movement, and behavior analysis for local surveillance in open and closed environments (iii) surface survey and imaging radar systems for environmental monitoring from surface, aerial and satellite platforms. The corresponding relevant problems of preliminary design are analyzed and addressed SPECIFIC • Knowledge and understanding: the student shall demonstrate knowledge and understanding of radar systems and their signal processing techniques. He/she must also understand how the basic principles and processing techniques are employed in different radar systems in their respective reference contexts. • Applying knowledge and understanding: The student must be able to apply the principles of operation and the radar signal processing techniques in a competent and critical way. The student must have adequate competences to both devise and support arguments, and to solve new detection and estimation problems. The student must set the radar systems in the appropriate position inside the wider systems for surveillance, navigation, monitoring, or Earth observation. • Making judgements: The student must be able to integrate knowledge and handle the complexity of the systems for surveillance, navigation, monitoring, or Earth observation. The student must be able to tackle a preliminary system design also in the presence of limited or incomplete information; reflect on the social and ethical responsibilities connected to the application of the technologies for surveillance, navigation, monitoring, or Earth observation. • Communication skills: The student must be able to describe the solutions selected while addressing the preliminary design of a radar system that fulfils assigned design specifications. • Learning skills: The student must be able to address the preliminary design of the systems in autonomous manner.
